13 years and he didn't hit the 100K subs!? People help this man! His content is super cool and very well teached! Thank you Roland for all this Years of goodness 🙏☺️

OMG you tutorials are great and its for free as well, which in Houdini universe is so rare. You definitely deserve more recognition and thank you for your work you doing here :). And I hope for more ;)

Thanks Pawel, I really appreciate it! 👍

I am very new to 3d in general and a complete noob in Houdini and your tutorials have help me a lot in learning the ropes and i am really thankfull. You are doing an amazing service to the community. Its baffling to me that you dont have at least a million subs mate!!

[@graphicINmotion]

Thank you very much for the kind comment!

Many thanks! Unfortunately the KZbin algorithm has a different opinion :)

Hi, thanks for this. This is a great technique, I would normally try using a vellum constraint property in the solver and then bring in the mops falloff and use that to adjust the restscale or restlength - the problem I always have is finding the exact settings to get the inflation to work - lots of frustration and retries when it doesn't inflate the way I want. Whereas this stopped method means can get the look of the inflation first just by adjusting settings in the cloth and pressure then use the stopped animation to animate it coming on.

[@graphicINmotion]

Additionally I often animate the restscale of the pressure in the beginning of the inflation transition using a constraint properties for even more control.

Finally. a new one! Thank you, Roland!

You are welcome!

I see you have a Maschine Studio behind you there!! I'm also a Maschine / Kontakt / Cubase user!! I'm just about to make the transition from max to houdini and looking for tutorials, mainly on particle physics and fluid sims but mainly geared towards making visualisations for my music... if you have any tutorials which are geared or could be geared to react to audio I'd be more than grateful as I have a lot of learning and adjusting ahead of me. Subbed :)

This is a fantastic tutorial, thank you for sharing. I was wondering what is the alterative setup for if I was unable to install MOPs due to strong IT setup?

[@graphicINmotion]

Thank you! You could use the "pyro source spread" node for example. You need to group a few starting points. Create a temperature attribute with a value of 1on these points. Then set up the source spread. You can then use the temperature attribute exactly as I use my "activate" attribute.

Many thanks!

[@IronMan-yg4qw]

NICE.

[@graphicINmotion]

Thanks!

[@philippwelsing9108]

Maybe helpful: Instead of painting the attribute all over again, I just did Undo until edge was back and used an Attribute Rename to name it restscale. Super quick.

[@graphicINmotion]

Thanks! That’s the way!

[@yesthatsam]

Great video, thanks a lot. I just wonder why you had to set @stopped beforehand ? I used the @activate directly in the vellum solver popwrangle with : float activate = point(0, 'activate', i@ptnum); i@stopped = activate > .5 ? 0 : 1;

[@graphicINmotion]

You are right. Thats more straight forward. Thanks for pointing that! 👍

[@imb1318]

please sir do more video about vellum. i am beginner. do you have beginner level video about vellum?

[@graphicINmotion]

Yes, check out my channel. I also have a huge course on Vellum on Patreon: www.patreon.com/collection/100535?

[@mosesmorgan1104]

could you also share how the shading has been done ?

[@graphicINmotion]

After the summer holidays I will try to find some time.

[@rendered_useless2093]

Hi Roland thanks for the tutorial After my MOPS Spread has finished, my simulation seems to lose pressure. It starts very inflated but by the time the "Spread" is finished it gets kind of floppy and deflated again. Do you know why this might be?

[@graphicINmotion]

Check your attribute values. Maybe something is off. But it’s difficult to analyze from the distance.
